Sixty-three people participated in a study to see if they were left-brain dominant or right-brain dominant. In the study, the people were also asked if they were left-handed or right-handed. The study revealed that 37 were left-brain dominant. The study also revealed that 21 were right-handed and right-brain dominant. Twenty-two people in the study were left-handed. What percentage of people were Left handed and Left-Brain dominate and Right handed and Left-Brain dominate? How many people were Left handed and Right-Brain dominate? What is the total number of people?

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

1 1/5

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
